<p>There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture and a pattern transfer used in that method. The decorative pattern is formed on a transfer sheet film as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film. The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the pattern transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity. Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern into the resin, with the pigments incorporated in the resin product and with most of the wax excluded from the product.</p> |
